Daily headlines emphasize the down side of technology: cyberattacks, election hacking and the threat of fake news. In response, government organizations are scrambling to understand how policy should shape technology's role in governance, security and jobs.

The Stanford Cyber Initiative is at the forefront of answering this question. Co-directors Michael McFaul, a professor of political science and director of the Freeman Spogli Institute for International Studies (FSI), and Dan Boneh, a professor of computer science and electrical engineering, tell us how the research behind the initiative helps define the role of policy in a world increasingly influenced by technology.

 

What is the goal of the Stanford Cyber Initiative?

McFaul: It is part of a broader cyber initiative that the Hewlett Foundation started several years ago. New technologies are changing the way we view security, the way we govern, the way we work. They're part of every aspect of life, and yet how we manage them, how we think about policy to regulate and enhance their use, has not caught up to the technology. Here at Stanford, we're focusing on the right policies and policy frameworks to address the new technological era we live in today.

Boneh: When we came to define cybersecurity, it turned out to include many different areas. It has to do with the security of computing technology, but it also includes implications to the workforce and U.S. economy. It includes security of our democracy and election systems. It includes security of our financial systems. The Cyber Initiative funds Stanford research in these areas that focuses on policy.

What's changing now that the Cyber Initiative has moved to the Freeman Spogli Institute for International Studies?

Boneh: I think it's wonderful the Cyber Initiative now has a home. With FSI, we have much more infrastructure support. It is also wonderful to have Mike's vision and leadership for the initiative. Mike has been a fantastic collaborator to work with on this.

McFaul: As the co-director with Dan, we've shaped it in a couple of different directions. We want to build on some strengths, and that means fewer areas that we focus on and greater resources to them. The three that I think are most prominent in our thinking are cybersecurity, governance and the future of work.

How does the Cyber Initiative address policy concerns?

McFaul: We require that all projects have an applied or policy component. We're trying to bridge the gap between the east side of campus and the west side. We want to see more computer scientists interacting with social scientists, lawyers and even philosophers, as there are many ethical and moral issues that need to be addressed.

For example, Amy Zegart and her team at the Center for International Security and Cooperation and the Hoover Institution hosted the Cyber Boot Camp. They assembled congressional staffers who deal with cybersecurity issues as well as other experts to discuss the most pressing challenges in cyberspace. What could be a more direct impact than educating them about these topics? In the realm of disinformation, a consortium of researchers affiliated with the Center on Democracy, Development and the Rule of Law are investigating the role that foreign governments played in our election, exploring what regulations should look like and the difference between First Amendment rights and foreign interference.

Then, there is wide disagreement about whether artificial intelligence is going to make us all better off or whether it's going to make us all unemployed. Scholars supported by the initiative are trying to address this. Understanding the relationship between new technologies and the workforce will eventually help federal, state and local government officials, as well as companies, schools and trade unions, to develop appropriate policies.

Boneh: On the technical side, many new technologies that can be beneficial to end users are not adopted because they do not match companies' incentives. Good tech policy can incentivize companies to adopt those beneficial technologies that improve privacy and security for clients or consumers. We want policies that promote computer security, but at the same time, we do not want to stifle innovation or greatly increase operating costs. At Stanford, we are in a unique position to make progress on these issues. We have a strong collaboration with the tech industry and the ears of policymakers in D.C.

Why is it important to work across disciplines when addressing cyber concerns?

Boneh: It brings together researchers who normally do not interact much. Every project that we fund crosses school boundaries. It brings faculty in the humanities to work with faculty in engineering, and that is not something that happens very often. You cannot do policy without understanding technology and effective technology needs to understand the policy implications. I recently taught a class with colleagues at the law school on cyber policy and the law. This is not something I would have done had it not been for the Cyber Initiative.

McFaul: Virtually every field is being impacted by new technologies, but expertise in cyber policy is not easily defined. I can tell you which are the five top journals in my field of political science – and if you want to advance your career, you publish there. I'm not sure I could name them in cyber policy. It feels to me like the technology is ahead of the policy, and a lot of the traditional security experts are not well-versed in computer science and engineering, including me. Conversely, those most expert in cyber technologies have paid little attention to national security, democracy or the future of capitalism. By bringing these researchers together, we increase understanding of technology's role across fields. 

How is the Cyber Initiative educating Stanford students?

McFaul: There is growing demand for courses that cross disciplines to address the rapidly evolving landscape of cybersecurity. We are training the next generation of leaders who will shape this field. Some of our new classes focus on cybersecurity and the law, fake news, privacy policies, how algorithms affect human perception, Facebook's foreign policy, and how technology affects elections. What's striking to me is that we're still in the early stages of incorporating cyber components into courses, curriculum and degrees.

Here at FSI, we have a master's degree in international policy studies, which will soon launch a new specialization in cyber policy. It will be one of the first in the country. But what is the content of such a program? It turns out that's a pretty contentious issue and we're wrestling with it right now.


The Stanford Cyber Initiative plans to fund research on cyber policy. Interested researchers should contact Allison Berke at aberke@stanford.edu.

John L. Hennessy, inaugural director of the Knight-Hennessy Scholars Program and president emeritus of Stanford, has been elected an international fellow of the Royal Academy of Engineering, the national academy for engineering in the United Kingdom.

Founded in 1976, the Royal Academy of Engineering brings together the most successful and talented engineers for a shared purpose: to advance and promote excellence in engineering. Earlier this week, the academy announced 50 new fellows, two international fellows, including Hennessy, and one honorary fellow.

Hennessy, a pioneer in computer architecture, said the honor held special significance because so many early pioneers in the field did their great work in England, from Alan Turing (1912-1954), a mathematician who conceived of modern computing and played a crucial role in the Allied victory over Nazi Germany in WWII, to Maurice Wilkes (1913-2010), a professor at Cambridge University who is considered the most important figure in the development of practical computing in the United Kingdom.

"I have had the pleasure of knowing many colleagues who are members of the Royal Academy of Engineering, including Wilkes, a colleague from Cambridge who I knew personally for many years," Hennessy said. "It is an honor to join such an august group."

Hennessy has won numerous awards for his work, including election to the National Academy of Engineering and the National Academy of Sciences. He is also a fellow of the American Academy of Arts and Sciences, the Association for Computing Machinery, and the Institute of Electrical and Electronics Engineers.

After stepping down as president of Stanford a year ago, Hennessy became the Shriram Family Director of the Knight-Hennessy Scholars Program, which is the largest fully endowed graduate-level scholarship program in the world. The program, which is currently located in the Littlefield Center, held a groundbreaking ceremony last spring for its future home, Denning House. Currently, the program is accepting applications for its first class of 50 scholars, who will begin their studies in the fall of 2018.

Hennessy joined Stanford's faculty in 1977 as an assistant professor of electrical engineering. In 1981, he drew together researchers to focus on a technology known as RISC (reduced instruction set computer), which revolutionized computing by increasing performance while reducing costs. Hennessy helped transfer this technology to industry. In 1984, he cofounded MIPS Computer Systems, now MIPS Technologies, which designs microprocessors.

Hennessy, who rose through the academic ranks at Stanford and became a full professor in 1986, served as chair of the Department of Computer Science and took the helm as dean of the School of Engineering in 1996. He became provost in 1999 and was inaugurated as Stanford's 10th president in 2000. He stepped down from the presidency in 2016.

As president, Hennessy fostered interdisciplinary collaboration, launching university-wide initiatives in human health, environmental sustainability, international affairs, the arts and creativity, and greatly expanding opportunities for multidisciplinary teaching and learning. Under his leadership, the campus underwent a physical transformation to support 21st-century research and teaching needs, including cutting-edge facilities for the Graduate School of Business, the Law School, the Science and Engineering Quadrangle, Stanford Medicine and the Arts District.

One day soon we may live in smart houses that cater to our habits and needs, or ride in autonomous cars that rely on embedded sensors to provide safety and convenience. But today's electronic devices may not be able handle the deluge of data such applications portend because of limitations in their materials and design, according to the authors of a Stanford-led experiment recently published in Nature.

To begin with, silicon transistors are no longer improving at their historic rate, which threatens to end the promise of smaller, faster computing known as Moore's Law. A second and related reason is computer design, say senior authors and Stanford EE professors Subhasish Mitra and H.-S. Philip Wong. Today's computers rely on separate logic and memory chips. These are laid out in two dimensions, like houses in a suburb, and connected by tiny wires, or interconnects, that become bottlenecked with data traffic.

Now, the Stanford team has created a chip that breaks this bottleneck in two ways: first, by using nanomaterials not based on silicon for both logic and memory, and second, by stacking these computation and storage layers vertically, like floors in a high-rise, with a plethora of elevator-like interconnects between the "floors" to eliminate delays. "This is the largest and most complex nanoelectronic system that has so far been made using the materials and nanotechnologies that are emerging to leapfrog silicon," said Mitra.

The team, whose other Stanford members include EE professors Roger Howe and Krishna Saraswat, integrated over 2 million non-silicon transistors and 1 million memory cells, in addition to on-chip sensors for detecting gases – a proof of principle for other tasks yet to be devised. "Electronic devices of these materials and three-dimensional design could ultimately give us computational systems 1,000 times more energy-efficient than anything we can build of silicon," Wong said.

First author Max Shulaker (PhD '16), who performed this work while a PhD candidate, is now an assistant professor at MIT and core member of its Microsystems Technology Laboratories. He explained in a single word why the team had to use emerging nanotechnologies and not conventional silicon technologies to achieve the high-rise design: heat. "Building silicon transistors involves temperatures of over 1,000 degrees Celsius," Shulaker said. "If you try to build a second layer on top of the first, you'll damage the bottom layer. This is why chips today have a single layer of circuitry."

The magic of the materials

The new prototype chip is a radical change from today's chips because it uses multiple nanotechnologies that can be fabricated at relatively low heat, Shulaker explained. Instead of relying on silicon-based transistors, the new chip uses carbon nanotubes, or CNTs, to perform computations. CNTs are sheets of 2-D carbon formed into nanocylinders. The new Naturepaper incorporates prior ground-breaking work by this team in developing the world's first all-CNT computer.

The memory component of the new chip also relied on new processes and materials improved upon by this team. Called resistive random-access memory (RRAM), this is a type of nonvolatile memory — meaning that it doesn't lose data when the power is turned off – that operates by changing the resistance of a solid dielectric material.

The key in this work is that CNT circuits and RRAM memory can be fabricated at temperatures below 200 Celsius. "This means they can be built up in layers without harming the circuits beneath," Shulaker says. "This truly is a remarkable feat of engineering," says Barbara De Salvo, scientific director at CEA-LETI, France, an international expert not connected with this project.

The RRAM and carbon nanotubes are built vertically over one another, making a new, dense 3-D computer architecture with interleaving layers of logic and memory. By inserting a plethora of wires between these layers, this 3-D architecture promises to address the communication bottleneck. "In addition to improved devices, 3-D integration can address another key consideration in systems: the interconnects within and between chips," Saraswat said.

To demonstrate the potential of the technology, the researchers placed over a million carbon nanotube-based sensors on the surface of the chip, which they used to detect and classify ambient gases.

Due to the layering of sensing, data storage and computing, the chip was able to measure each of the sensors in parallel and then write directly into its memory, generating huge bandwidth without risk of hitting a bottleneck, because the 3-D design made it unnecessary to move data between chips. In fact, even though Shulaker built the chip using the limited capabilities of an academic fabrication facility, the peak bandwidth between vertical layers of the chip could potentially approach and exceed the peak memory bandwidth of the most sophisticated silicon-based technologies available today.

System benefits

This provides several simultaneous benefits for future computing systems.

"As a result, the chip is able to store massive amounts of data and perform on-chip processing to transform a data deluge into useful information," Mitra says.

Energy efficiency is another benefit. "Logic made from carbon nanotubes will be ten times more energy efficient as today's logic made from silicon," Wong said. "RRAM can also be denser, faster and more energy-efficient than the memory we use today."

Thanks to the ground-breaking approach embodied by the Nature paper, the work is getting attention from leading scientists who are not directly connected with the research. Jan Rabaey, a professor of electrical engineering and computer sciences at the University of California, Berkeley, said 3-D chip architecture is such a fundamentally different approach that it may have other, more futuristic benefits to the advance of computing. "These [3-D] structures may be particularly suited for alternative learning-based computational paradigms such as brain-inspired systems and deep neural nets," Rabaey said, adding, "The approach presented by the authors is definitely a great first step in that direction."

 

This work was funded by the Defense Advanced Research Projects Agency, National Science Foundation, Semiconductor Research Corporation, STARnet SONIC and member companies of the Stanford SystemX Alliance.

The next generation of feature-filled and energy-efficient electronics will require computer chips just a few atoms thick. For all its positive attributes, trusty silicon can't take us to these ultrathin extremes.

Now, electrical engineers at Stanford have identified two semiconductors – hafnium diselenide and zirconium diselenide – that share or even exceed some of silicon's desirable traits, starting with the fact that all three materials can "rust."

"It's a bit like rust, but a very desirable rust," said Eric Pop, an associate professor of electrical engineering, who co-authored with post-doctoral scholar Michal Mleczko a paper that appears in the journal Science Advances.

The new materials can also be shrunk to functional circuits just three atoms thick and they require less energy than silicon circuits. Although still experimental, the researchers said the materials could be a step toward the kinds of thinner, more energy-efficient chips demanded by devices of the future.

Silicon's strengths
Silicon has several qualities that have led it to become the bedrock of electronics, Pop explained. One is that it is blessed with a very good "native" insulator, silicon dioxide or, in plain English, silicon rust.

Exposing silicon to oxygen during manufacturing gives chip-makers an easy way to isolate their circuitry. Other semiconductors do not "rust" into good insulators when exposed to oxygen, so they must be layered with additional insulators, a step that introduces engineering challenges. Both of the diselenides the Stanford group tested formed this elusive, yet high-quality insulating rust layer when exposed to oxygen.

Not only do both ultrathin semiconductors rust, they do so in a way that is even more desirable than silicon. They form what are called "high-K" insulators, which enable lower power operation than is possible with silicon and its silicon oxide insulator.

As the Stanford researchers started shrinking the diselenides to atomic thinness, they realized that these ultrathin semiconductors share another of silicon's secret advantages: the energy needed to switch transistors on – a critical step in computing, called the band gap – is in a just-right range. Too low and the circuits leak and become unreliable. Too high and the chip takes too much energy to operate and becomes inefficient. Both materials were in the same optimal range as silicon.

All this and the diselenides can also be fashioned into circuits just three atoms thick, or about two-thirds of a nanometer, something silicon cannot do.

The combination of thinner circuits and desirable high-K insulation means that these ultrathin semiconductors could be made into transistors 10 times smaller than anything possible with silicon today.

"Silicon won't go away. But for consumers this could mean much longer battery life and much more complex functionality if these semiconductors can be integrated with silicon," Pop said.

More work to do
There is much work ahead. First, Mleczko and Pop must refine the electrical contacts between transistors on their ultrathin diselenide circuits. "These connections have always proved a challenge for any new semiconductor, and the difficulty becomes greater as we shrink circuits to the atomic scale," Mleczko said.

They are also working to better control the oxidized insulators to ensure they remain as thin and stable as possible. Last, but not least, only when these things are in order will they begin to integrate with other materials and then to scale up to working wafers, complex circuits and, eventually, complete systems.

"There's more research to do, but a new path to thinner, smaller circuits – and more energy-efficient electronics – is within reach," Pop said.

It looks like a regular roof, but the top of the Packard Electrical Engineering Building at Stanford University has been the setting of many milestones in the development of an innovative cooling technology that could someday be part of our everyday lives.

Since 2013, Shanhui Fan, professor of electrical engineering, and his students and research associates have employed this roof as a testbed for a high-tech mirror-like optical surface that could be the future of lower-energy air conditioning and refrigeration.

Research published in 2014 first showed the cooling capabilities of the optical surface on its own. Now, Fan and former research associates Aaswath Raman and Eli Goldstein, have shown that a system involving these surfaces can cool flowing water to a temperature below that of the surrounding air. The entire cooling process is done without electricity.

"This research builds on our previous work with radiative sky cooling but takes it to the next level. It provides for the first time a high-fidelity technology demonstration of how you can use radiative sky cooling to passively cool a fluid and, in doing so, connect it with cooling systems to save electricity," said Raman, who is co-lead author of the paper detailing this research, published in Nature Energy Sept. 4, 2017.

Together, Fan, Goldstein and Raman have founded the company SkyCool Systems, which is working on further testing and commercializing this technology.

Radiative sky cooling is a natural process that everyone and everything does, resulting from the moments of molecules releasing heat. You can witness it for yourself in the heat that comes off a road as it cools after sunset. This phenomenon is particularly noticeable on a cloudless night because, without clouds, the heat we and everything around us radiates can more easily make it through Earth's atmosphere, all the way to the vast, cold reaches of space.

"If you have something that is very cold – like space – and you can dissipate heat into it, then you can do cooling without any electricity or work. The heat just flows," explained Fan, who is senior author of the paper. "For this reason, the amount of heat flow off the Earth that goes to the universe is enormous."

Although our own bodies release heat through radiative cooling to both the sky and our surroundings, we all know that on a hot, sunny day, radiative sky cooling isn't going to live up to its name. This is because the sunlight will warm you more than radiative sky cooling will cool you. To overcome this problem, the team's surface uses a multilayer optical film that reflects about 97 percent of the sunlight while simultaneously being able to emit the surface's thermal energy through the atmosphere. Without heat from sunlight, the radiative sky cooling effect can enable cooling below the air temperature even on a sunny day.

The experiments published in 2014 were performed using small wafers of a multilayer optical surface, about 8 inches in diameter, and only showed how the surface itself cooled. Naturally, the next step was to scale up the technology and see how it works as part of a larger cooling system.

Putting radiative sky cooling to work
For their latest paper, the researchers created a system where panels covered in the specialized optical surfaces sat atop pipes of running water and tested it on the roof of the Packard Building in September 2015. These panels were slightly more than 2 feet in length on each side and the researchers ran as many as four at a time. With the water moving at a relatively fast rate, they found the panels were able to consistently reduce the temperature of the water 3 to 5 degrees Celsius below ambient air temperature over a period of three days.

The researchers also applied data from this experiment to a simulation where their panels covered the roof of a two-story commercial office building in Las Vegas – a hot, dry location where their panels would work best – and contributed to its cooling system. They calculated how much electricity they could save if, in place of a conventional air-cooled chiller, they used vapor-compression system with a condenser cooled by their panels. They found that, in the summer months, the panel-cooled system would save 14.3 megawatt-hours of electricity, a 21 percent reduction in the electricity used to cool the building. Over the entire period, the daily electricity savings fluctuated from 18 percent to 50 percent.

Broad applicability in the years to come
Right now, SkyCool Systems is measuring the energy saved when panels are integrated with traditional air conditioning and refrigeration systems at a test facility, and Fan, Goldstein and Raman are optimistic that this technology will find broad applicability in the years to come.

The researchers are focused on making their panels integrate easily with standard air conditioning and refrigeration systems and they are particularly excited at the prospect of applying their technology to the serious task of cooling data centers.

Fan has also carried out research on various other aspects of radiative cooling technology. He and Raman have applied the concept of radiative sky cooling to the creation of an efficiency-boosting coating for solar cells. With Yi Cui, a professor of materials science and engineering at Stanford and of photon science at SLAC National Accelerator Laboratory, Fan developed a cooling fabric.

"It's very intriguing to think about the universe as such an immense resource for cooling and all the many interesting, creative ideas that one could come up with to take advantage of this," he said.
